dubbo-zookeepr-spring's Introduction

Dubbo-Zookeepr-Spring

本例子是在windows7下运行，Linux的运行效果未展示。

本例子使用单例模式，未配置Zookeeper集群，方便入门学习。

学习本教材的你应该有一定的java基础，为了方便我在例子中使用Maven构建工具，不需要找jar包的痛苦了

由于Zookeeper太大，我把zookeeper压缩了，解压后，修改conf下的配置文件下的 zoo.cfg文件，在zookeeper官网下载到zookeeper时是没有这个文件的，将zoo_sample.cfg复制一个为zoo.cfg的文件即可。

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=D:\\zookeeper\\data
dataLogDir=D:\\zookeeper\\log
#dataDir=/tmp/zookeeper
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1

修改dataDir和dataLogDir即可，修改后需要创建相应的文件夹，及存储日志和数据，否则启动zookeeper会报错，在zookeeper文件夹下的bin文件夹下双击zkServer.cmd可以启动zookeeper，启动成功后可以看到

这就证明zookeeper启动成功，不要关闭，进行下一步

下面开始进如生产者和消费者的步骤，首先启动生产者也就是Provider的main方法,

System.in.read(); // 按任意键退出

是为了防止程序运行后直接退出

运行后可以在控制台看到

下一步启动消费者程序及Consumer的main方法，可以在控制台看到如下内容证明成功获取生产者中的数据
